MORTISE-MOLID Application filed October 26, 1918.

To all whom it may concern.

Be it known that I, W'ILLIAM E. Boner, a citizen of the United States'of America, residing at Grand Ra ids, in the county of Kent and State of ichigan, have invented certain new and useful Improvements in. Mortise-Molds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a mortise mold adapted to be applied to the mold wheel of a linotype casting machine for the production of an open casting of type metal in which a regular type slug castby the usual molds of linotype machines may be inserted, the open casting or mortise at one edge being alsoformed with a raised border such that the mortise with the slug therein whelri W1 produce what is known as a box hea ing several of which are ordinarily used in each issue of a newspaper. Heretofore it has been the usual practice to set up the box heading by means of suitable characters and spacers. the operation taking considerable time. W'ith my invention, the open mortises made with the mold of my invention may be cast rapidly and the slugs containing the cast heading to go within. the mortise are readily and rapidly cast in the usual manner, whereby the production: of box headings may be greatly facilitated. It is the object and purpose of this invention to produce a mold which will produce the mortises for receiving the type slugs, said mold being applicable to mold wheels of linotype machines, and with which box heading mortises may be cast with great rapidity.

To this end I have made the construction illustrated in the accompanying drawings, in which,

Figure 1 is a front elevation of the mold.

Fig. 2 is a lower plan view thereof.

Fig. 3 is a view substantially on the line 3-3 of Fig. 1 looking in the direction indicated by the arrows at 3. 3.

Fig. 7 is an under plan thereof.

Fig. 11 is a front view of a mortise with a type slug fitted therein.

Figs. 13 and 14 are, respectively, an elevation and end view of the type slug adapted to fit in the mortise produced by this mold.

Fig. 15 is a front elevation of the grooved matrix which comes in front of the mold during the operation of casting the box; and

Fig. 16 is an end elevation thereof.

Like reference characters refer to like parts in the different views of the drawings.

In the construction of the mold an upper member 1 is provided which has a smooth under face 2, said member being known as the mold proper. At each end of the mold spacers 3 and 4 are located the same being readily detachable from the mold and capable of replacement by spacer members of different lengths for different len he of castings. At each end of the mold ngeis 5 project. being adapted to enter slots 6 in the ends of the mold cap 7 for releasably holding the mold and cap together. This cap has an upper surface 8 on wh ch a plurality of tapered grooves 9 are out for helping the withdrawal of the casting from the mold. These members of the mold, the mold proper and the cap therefor are not new. being used in the linotype machine for the production of type slugs, the face 8 being spaced from the face 2 by suitable spacers such as 3 and 4 and the metal forced into themold from behind and against the matrices iuthe mold face of the linotype machine for roducing type slugs, as is well understo by all familiar with linotype casting machines.

In my invention two spacers 10 of the same length as the spacers 3 and 4 are lo cated at the ends of the cap] against the face 8, and against such spacers a bar 11 is placed. the same extending the full length of the mold and having deep slots 12 cut. from the front edge of the bar, leaving only a relatively narrow connecting neck l3a}t bottom of each slot. Slote itiiqe located se.

that when the (H11) is attached to the mold the inner ends of spacers 1i, 4: and 1U he in :ilineinent with those parts of the her it t irnnng the outer sides of sand slots. lhe

Mr 11 with the interposed spacial-s ll) are fitz llll'ttl to the cap h screws i l. in this manner there is made it mold having it central (Ul't 11" between the slots i2 and located between open spaces 15 and 16 which spiieee eonnnuniente with the slots 12 so that on introduetion of molten type metal into the mold an open casting is made where the metal has tilled spaces l5, l6 and slots 12.

The metal is forced into the mold from hehind entering the spares l5 and 1t) and. flowing around the net-ks 13 to fill the slots [2. The casting or mortise made inoludee odes ii and i8 :ind ends 19, the side 18 having H plurality of tapering l'l JS 2i thereon as shown from metal entering the grooves it The ends if have recesses 20 where the newly-a iii are lomted. and an open spare is made in whieh the type slug earr ng the iypi: iiinrin'ters of ill" title for the in); heading may he positioned. 'l hv mold rim-e ol' the iinotype machine in equipped with 21 unit: is: 2 inning :1 groove 2U whiih when' the inetnl is forced into it makes n raised horder GI on the front edges of the sides and ends oi the mortise casting made and which liee in the same plane with the feces of the type characters so that, when ink is applied and the mine impressed on paper ii heading having a continuous ineiosing border is made. The type slug 24 is of the usual elnirzwter east in linotype nuii'hinee, and the thicknee -i of the bar 11 sui-h that the opening made by casting around the Pore ll is just suiiieient to receive the slug.

With 11 mold made in illjtfil'tlzllltfi: with my invention, the formation of lmX h ailing moriieee very expeditious. it lHJlilfl pow Hilde to form them at the rate ot three or t ur a minute. eneh being perleei in every respect and in Wllitl any desired heading may be placed. By changing the length of the core portion ll, that is by dili'ei'ently loi'utin the slots 12 in the bar 1] i and using eorresponding lengths of spaeers 1i 4. and 10, box heading mortises may he made of diii'erent lengths as desired, and the thickness of the hair 11 of course is rontrolling 2th to the size of type slug which may he loouted in the mortise whieh thiek'nees of her may be readily changed Without changing the operation of the mold.
